ES503 is the first born of brand new Entertainment System series, specifically created by Italian manufacturer dB Technologies in order to pack its long time active speaker expertise into a multifunctional, portable, space-saving, user-friendly yet powerful system. A complete three-element system which adapts to several uses (and thousands of different users), thanks to a built-in digital mixer, a OLED display user interface and a Bluetooth audio receiver.
More details from RCF USA (www.rcf-usa.com):
This initial product introduction in the series is the ES503, a 1000-watt tri-amped sound system composed by two satellite modules featuring four 3” full-range drivers plus a master 12” subwoofer.
Compact and portable, the dB Technologies’s components and design allow an amazing SPL/size ratio: 3.75”x14”x6” at 3 pounds for the tops and 18.25”x15.75”x17” at 16.5 pounds for the subwoofer. The system provides an overall max SPL of 121 db.
A dB Technologies Digipro G3® amp module with auto-range PSU powers the subwoofer module that has a three-channel mixer with Bluetooth connection built-in. A powerful DSP manages all function of the on-board digital mixer, making the ES503 a real gem in terms of sound performance and versatility.
The internal design of the satellite top modules allows an asymmetrical vertical coverage (thanks to the Logarithmic Curved Column Array technology) and a unique “double ringed” phase plug widens the horizontal coverage and guarantees a perfect voice intelligibility. This allows ES503 to adapt to any situation, both with a seated or standing audience.
3 configurations
The ES503 is the most eclectic among portable systems on the market today, allowing three different configurations suitable for hundreds of different occasions:
1: MONO MODE
The two satellites are connected top-on-top (thanks to a quick and easy slide connection system) and are placed on the subwoofer through a 25 mm pole included in the package.
2: STEREO MODE
Provides you a stereo mode choice where either each satellite is placed on a tripod, or one is pole mounted on top of subwoofer while other satellite module is placed on a tripod.
3: DOUBLE COLUMN MODE
This is where the ES503 system in mono mode becomes the master for a second ES503 feeding the signal thanks to the integrated balanced output channel. This way, both system are driven by the master’s on board mixer and any setup is guided through the master’s OLED display.
Let’s take a quick look at the ES503 system:
- A Fast Speaker Connection
For mono configurations, the two tops can be easily connected top to top. The enclosure of the two satellites embeds a slide connection system, which assures perfect top-to-top matching without the risk of incorrect assembly and includes the electrical connection between the two tops. The “A” satellite receives the powered signal from the subwoofer through a 4-poles male Speakon™ connector and relaunch the audio to the “B” top.
For stereo configurations, both tops are connected to the sub through a Speakon™ Connector.
- On-Board 3 Channel Mixer
The ES503 is equipped with a three-channel mixer controlled by a DSP. The first channel features a MIC/instrument balanced/unbalanced combo connector with an adjustable anti-feedback filter, impedance compensation and microphone gain with 3 positions (0, +10, + 20dB). The second and third channels are LINE inputs with balanced/unbalanced combo connector. The system is provided with several preset equalizations, and each user can create and save its own custom equalization.
- Customizable Balanced Output Channels
The balanced AUX/MIX output can be used as a direct link, or, alternatively, as an AUX output. In this case, you can actually feed a stage monitor or another speaker for which a custom separate mix is needed. In addition to that, a dedicated notch filter is available in order to avoid any feedback.
When in double column mode, this output acts as a source of a second ES system providing left or right content.
- Integrated Audio Bluetooth Module
The ES503 is equipped with a built-in Bluetooth™ stereo module, which receives audio from devices such as mobile phones, tablets or any other audio device with a Bluetooth™ connection.
- User Friendly OLED display
The ES503 is incredibly simple to set up and comes with an intuitive wizard that guides the user step-by-step and automatically configures the system according to the application. The advanced graphical interface allows to enter the heart of the system, recall configuration presets, adjust levels, EQ and create a pre/post gain mix for different purposes. A rotary encoder with a switch allows to control any operation easily and quickly.
- 12” Bass-reflex Subwoofer
The bass-reflex subwoofer houses a 12” woofer and the amplifier module. In addition to the input connectors and controls of the user-interface, there are two Speakon outputs and a VDE power connector. The enclosure, sturdy and stylish, is made of birch plywood coated with a durable scratch-resistant black coat, which makes it truly road-ready. Two handles (one per side) help easy transport.
The ES503 bundle includes a subwoofer, two tops, a D25mm pole and a Speakon/Speakon cable to connect the sub to the top. The speaker pole is in two segments for easy transport. The system include a group of accessories, such as two D25mm tripod stands with a dedicated transport bag, a bag to carry two tops and a D25mm pole, a bag for the 12” subwoofer, a trolley, a cable kit with two 7-meter Speakon/Speakon cables.
A stereo kit comprising two tripods plus 7m Speakon/Speakon cables and a transport kit comprising a sub bag plus top bag plus trolley are also available.
RCF USA will introduce the dB Technologies ES503 in the United States at Infocomm 2015 in Orlando, Florida June 17-19. The RCF USA booth number is 1167 with product demonstrations on the odd hours in demo room 102A.
